The first scale of electronegativity was developed by Linus Pauling and on his scale neon has a value of (no data) on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine). Electronegativity has no units but "Pauling units" are often used when indicating values mapped on to the Pauling scale.

Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. The higher the value of the electronegativity, the more strongly that element attracts the shared electrons.

And the element which has the lowest electronegativity value is Francium in 0.7 χ. Lithium. 0.98. 22.99.

Because fluorine is the most electronegative element, the electrons tend to "hang out" more toward the fluorine atom when fluorine is covalently bonded to other atoms.

Electronegativity is a chemical property which describes how well an atom can attract an electron to itself. Values for electronegativity run from 0 to 4. Electronegativity is used to predict whether a bond between atoms will be ionic or covalent. It can also be used to predict if the resulting molecule will be polar or nonpolar.

Ne + e – → Ne – – ∆H = Affinity = — kJ/mol. To use electron affinities properly, it is essential to keep track of sign. When an electron is added to a neutral atom, energy is released. This affinity is known as the first electron affinity and these energies are negative. By convention, the negative sign shows a release of energy.

In HF, the fluorine atom is much more electronegative than the hydrogen atom.

Why does fluorine have a higher Rank the following elements by increasing electronegativity: sulfur, oxygen, neon , aluminum.

Trends in electronegativity across a period. As you go across a period the electronegativity increases. The chart shows electronegativities from sodium to chlorine - you have to ignore argon. It doesn't have an electronegativity, because it doesn't form bonds. Trends in electronegativity down a group. As you go down a group, electronegativity

Therefore an experiment to measure their bond energies is not possible, and there is no way to actually calculate the electronegativity.
